Impulsivity partially mediates the relationship between BIS/BAS and risky health behaviors

Several theorists have suggested that impulsivity can be understood as a joint function of the behavioral approach (BAS) and behavioral inhibition systems (BIS). After resolving questions concerning the measurement of impulsivity and BAS, this study examined the relationships among risky health behaviors, impulsivity, BIS, and BAS. Utilizing a sample of undergraduates (N = 904), a structural model was tested in which BAS and BIS predicted impulsivity, which, in turn, predicted risky behavior. Fit indices were acceptable, but not good. A modified version of the model showed a statistically significant negative relationship between BAS and risky behaviors. However, the fit indices were not unequivocally supportive of the need to include that path. Overall, the data suggest that impulsivity is the joint result of countervailing motivational forces and that it partially or fully mediates the influence of BIS and BAS on risky health behavior.     

How we Became the Schmams: Conceptualizations of Fairness in the Decision-Making Process for Latina/O Children

The current study examines 16 Latina/o fifth grade children's desires for a decision-making structure within a youth participatory action research (yPAR) program. When given the choices of consensus, majority rule, authoritarian rule, delegation, and random choice models, children chose random choice. Procedural, distributive and emotional justice were heavily weighted in their reasoning around fairness and decision making. Many thought random choice offered the best alternative because it flattened power hierarchies so that each child would, at some point, have the power to make a decision. Additionally, children argued that the neutrality of random choice allowed them to sidestep interpersonal tensions. Implications include how social identities inform definitions of fairness and how yPAR programs should work with youth around how they will make decisions.     

Flexible feature-based inhibition in visual search mediates magnified impairments of selection: evidence from carry-over effects under dynamic preview-search conditions

Evidence for inhibitory processes in visual search comes from studies using preview conditions, where responses to new targets are delayed if they carry a featural attribute belonging to the old distractor items that are currently being ignored-the negative carry-over effect (Braithwaite, Humphreys, & Hodsoll, 2003). We examined whether inhibition was applied in the same manner across different types of displays or whether the inhibitory weighting applied to different features varied with their utility for the search task. To test this, we present the first empirical investigation of negative carry-over effects under the ecologically valid conditions of dynamic visual search. Experiment 1 investigated preview search using dynamic moving and static displays. Detection was very poor when new targets carried the color of the old distractors, and this negative carry-over effect was significantly exaggerated with moving, compared with static, displays. Experiments 2a and 2b demonstrated that this effect could not be attributed to an increased role of preattentive grouping between new and old items for dynamic displays. Collectively, the findings suggest that feature-based inhibition contributes strongly to preview search through dynamic displays, and this leads to an amplified attentional blindness to new targets. The data specifically indicate that inhibitory processes in search differentially weight color and location in moving and static displays, and that feature-based inhibition may underlie many instances of sustained inattentional blindness in everyday life.     

Dispositional mindfulness moderates the relation between neuroticism and depressive symptoms

Negative emotional reactivity as measured by neuroticism has been shown to be an important risk factor for the development of depressive symptoms. This study investigated whether the ability to be mindful can protect against the negative effects of this temperamental vulnerability. An English community sample of N = 144 individuals who had completed a neuroticism questionnaire six years previously were assessed for current depressive symptoms and dispositional levels of mindfulness at points of assessment approximately one year apart. Dispositional mindfulness moderated the relation between neuroticism and current depressive symptoms: Neuroticism was significantly related to depression in those with low to medium levels of dispositional mindfulness but not in those with relatively high levels of mindfulness. Further analyzes focusing on particular mindfulness skills indicated that this effect was carried mostly by the ability to describe inner experience. The results suggest that dispositional mindfulness and particularly the ability to describe inner experience are helpful in dealing with negative emotional reactivity in a way that reduces the likelihood of depressive symptoms to develop.     

Stakeholders’ Opinions on the Implementation of Pediatric Whole Exome Sequencing: Implications for Informed Consent

Advances in whole genome and whole exome sequencing (WGS/WES) technologies have led to increased availability in clinical settings. Currently, there are few guidelines relating to the process and content of informed consent for WGS/WES, nor to which results should be returned to families. To address this gap, we conducted focus groups to assess the views of professionals, parents, and adolescents for the future implementation of WES. The discussions assessed understanding of the risks and benefits of WES, preferences for the informed consent discussion, process for return of results, and the decision-making role of the pediatric patient. Professional focus group participants included bioethicists, physicians, laboratory directors, and genetic counselors. Parent focus groups included individuals with children who could be offered sequencing due to a potential genetic cause of the child’s condition. On-line discussion groups were conducted with adolescents aged 13–17 who had a possible genetic disorder. We identified discrepancies between professionals and patient groups regarding the process and content of informed consent, preference for return of results, and the role of the child in decision-making. Professional groups were concerned with the uncertainty regarding professional obligations, changing interpretation in genomic medicine, and practical concerns of returning results over time. Parent and adolescent groups focused on patient choice and personal utility of sequencing results. Each group expressed different views on the role of the child in decision-making and return of results. These discrepancies represent potential barriers to informed consent and a challenge for genetic counselors regarding the involvement of pediatric patients in decision-making and return of results discussions.     

What's mom got to do with it? Contributions of maternal executive function and caregiving to the development of executive function across early childhood

Executive functions (EFs; e.g. working memory, inhibitory control) are mediated by the prefrontal cortex and associated with optimal cognitive and socio‐emotional development. This study provides the first concurrent analysis of the relative contributions of maternal EF and caregiving to child EF. A group of children and their mothers (n = 62) completed age‐appropriate interaction (10, 24, 36 months) and EF tasks (child: 24, 36, and 48 months). Regression analyses revealed that by 36 months of age, maternal EF and negative caregiving behaviors accounted for unique variance in child EF, above and beyond maternal education and child verbal ability. These findings were confirmed when using an early child EF composite‐our most reliable measure of EF – and a similar pattern was found when controlling for stability in child EF. Furthermore, there was evidence that maternal EF had significant indirect effects on changes in child EF through maternal caregiving. At 24 months, EF was associated with maternal EF, but not negative caregiving behaviors. Taken together, these findings suggest that links between negative caregiving and child EF are increasingly manifested during early childhood. Although maternal EF and negative caregiving are related, they provide unique information about the development of child EF.

National Guard Couples Communicating During Deployment: The Challenge of Effective Connection

Communication during a combat deployment has changed significantly in current times. Couples can now communicate with each other frequently and through multiple modes. Despite this greater availability of communication options, there remain unanswered questions related to how healthy deployment communication is best achieved between couples, particularly regarding navigating the uncertainty of deployment. In this qualitative study, we report on the experiences of 31 National Guard couples who endured a combat deployment in support of Operation Enduring Freedom. Couples were interviewed three months after the soldier returned from deployment. Through the lens of relational turbulence theory, we provide a conceptual framework related to effective and non-effective deployment communication, along with structural communication barriers in the military that may negatively affect the mental well-being of partners. Finally, we provide recommendations to guide couples through these difficult deployments.

Do Teachers maintain their Expectation Bias for students? A longitudinal investigation

Whether teachers maintain their expectation bias for students over time is crucial for understanding self-fulfilling prophecy effects. However, the stability of teacher expectation bias has been largely ignored in the literature. We examined the stability of teacher expectation bias across a sample of teachers and the change trajectories of teacher expectation bias across high-, medium-, and low-expectation teacher groups across all teachers and in the curriculum areas of mathematics, Chinese, and English. Our analyses were based on two-year longitudinal data with four time points from 567 Chinese senior high school students and their 50 teachers. The results showed that across all teachers, teacher expectation bias at the individual student level was dynamic over time. That is, teachers seemed to adjust their initial expectation bias in the first few months but then maintained the adjusted expectation bias afterwards. However, when students moved from Grade 11 to Grade 12 (the last year of high school), teachers seemed to change their expectation bias again. The evidence from HLM analyses further supported these results. That is, all the high- and low-expectation teachers alleviated their initial expectation bias significantly in the first six months and then adhered to their adjusted expectation bias. However, when students moved to the last year of high school, some high- and low-expectation teachers’ expectation biases were volatile again. Nevertheless, most high- and low-expectation teachers (except for Chinese low-expectation teachers) tended to either over-estimate or under-estimate their students across two school years. Further, compared to Chinese and mathematics teachers, English teachers’ biases seemed to be even more stable. Our findings suggested that some teachers consistently over- or under-estimated their students over an extended time period and this could have implications for student outcomes.
